Question

我想拉伸此窗口的Groupbox（高度）。我无法让它发挥作用。我究竟做错了什么？我想要的是groupbox延伸到窗口的高度，但第一列不伸展。

    <!-- PLAYER A -->
    <Border Grid.Row="0" Grid.Column="0" x:Name="PlayerA" Height="145" VerticalAlignment="Center">
        <Grid Height="145" VerticalAlignment="Top">
            <GroupBox x:Name="grpPlayerA" Header="Player A" Margin="10,14,0,0" RenderTransformOrigin="0.035,-0.717" Height="127" VerticalAlignment="Top">
                <Grid HorizontalAlignment="Center" VerticalAlignment="Center">
                    <Label x:Name="lblArtistA" Content="VENGABOYS" HorizontalAlignment="Left" Margin="3,3,0,0" VerticalAlignment="Top"/>
                    <Label x:Name="lblTitleA" Content="TO BRAZIL" HorizontalAlignment="Left" Margin="3,27,0,0" VerticalAlignment="Top"/>
                    <ProgressBar x:Name="prgPlayerA" HorizontalAlignment="Left" Height="15" Margin="5,53,0,0" VerticalAlignment="Top" Width="212"/>
                    <Image x:Name="imgPlayerA" HorizontalAlignment="Left" Height="62" Margin="220,6,0,0" VerticalAlignment="Top" Width="81"/>
                    <Button x:Name="btnPlayerAPlay" Content="Play" HorizontalAlignment="Left" Margin="5,79,0,0" VerticalAlignment="Top" Width="75"/>

提前感谢它会很棒！

Answer 1

如果您希望GroupBox的高度延伸，为什么VerticalAlignment Top？将其切换为Stretch，它应该可以正常工作。

Answer 2

请参阅本说明： WPF Groupbox height needs to change dynamically?

底线 - 将宽度和高度设置为“自动”（删除它们拥有的值），如果你需要它也可以设置VerticalAlignment / Horizontal一个“Stretch”

WPF网格不会拉伸它的高度
